In which type of chemical reaction do two or more substances combine to form one substance?

Chemistry

WINSTONCH [101]3 years ago
6 0

Explanation:

A reaction in which two or more substances combine together to form a single product is known as synthesis reaction.

For example, C + O_{2} \rightarrow CO_{2}

     or,        H_{2} + \frac{1}{2}O_{2} \rightarrow H_{2}O

During synthesis reaction, heat or light are released in the form of energy. Therefore, synthesis reactions are exothermic in nature.

Pepsi [2]

Answer:

The K_{m} of a substrate will be "10 μM".

Explanation:

The given values are:

E_{t} = 20 \ nM

[Substract] = 40 \ \mu M

K_{cat}=600 \ s^{-1}

Reaction velocity, Vo=9.6 \ \mu M s^{-1}

As we know,

⇒  Vo=\frac{K_{cat}[E_{t}][S]}{K_{m}+[S]}

On putting the estimated values, we get

⇒  9.6=\frac{600\times 20\times 10^{-3}\times 40}{K_{m}+40}

⇒  K_{m}+40=\frac{600\times 20\times 10^{-3}\times 40}{9.6}

⇒  K_{m}+40=50

On subtracting "40" from both sides, we get

⇒  K_{m}+40-40=50-40

⇒  K_{m}=10 \ \mu M

What is the sign of the heat change for an exothermic reaction? for an endothermic reaction?
Julli [10]

A system that releases heat to the surroundings, an exothermic reaction, has a negative ΔH by convention, because the enthalpy of the products is lower than the enthalpy of the reactants of the system. The enthalpies of these reactions are less than zero, and are therefore exothermic reactions
